Adjustment rule generation for static systems

In many industrial fields, there are still difficulties in adjusting parameters of nonlinear systems. In order to cope with the difficulties, the paper proposes that adjustment should be divided into choosing appropriate parameters, calculating the amount of modification of the chosen parameters, and dealing with nonlinear phenomena. An adjustment rule which describes how to choose the appropriate parameter in every situation is generated by using characteristics of influences of parameters. The calculation for the modification is carried out in a trial just before the chosen parameter is really modified for adjustment. Nonlinear phenomena during adjustment can be categorized into vibration and inert-zone, and they should be evaded by extra treatments prepared beforehand. In addition, a sufficient condition for convergence to the desired state is explained in the case that the characteristics of the object system are known. Finally, an example shows that the proposed method is applicable to unknown nonlinear static systems
